NaCl – Networking and Cryptography Library — open source high-level crypto library. NaCl (pronounced “salt”) is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl’s goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed. Creator of qmail is one of the developers. (via Simon Willison)
